Caroline raspberry is a popular choice for home gardeners
The Caroline raspberry (Rubus idaeus ‘Caroline’) is a popular choice for home gardeners due to its abundance of large, flavorful fruit and its resistance to common diseases. This paper will explore the characteristics, planting requirements, and care of the Caroline raspberry, making it a valuable resource for those interested in growing this delectable berry.
Characteristics
- Fruit: The Caroline raspberry produces large, red berries with a rich, full flavor. These berries are excellent for fresh eating, baking, jams, and freezing.
- Everbearing: Unlike traditional summer-fruiting raspberries, Caroline is an everbearing variety. This means it produces fruit on new canes (primocanes) in late summer and fall, and again on the same canes (floricanes) the following spring/early summer.
- Disease Resistance: Caroline boasts good resistance to root rot and yellow rust, common problems for raspberry plants.
- Growth Habit: This vigorous raspberry variety has upright canes that can reach 4-9 feet tall and 2-4 feet wide.
Planting Requirements
- Climate: Caroline thrives in USDA zones 3 to 7. It performs well in both the East and Midwest regions of the United States. While it tolerates warmer temperatures, it does not fare well in excessive heat and drought.
- Sun: For optimal fruit production, plant Caroline raspberries in a location receiving full sun. They can tolerate some light shade, but this may reduce yield.
- Soil: These plants prefer well-drained, slightly acidic soil with a pH between 6.0 and 6.8. Amending the soil with organic matter before planting can improve drainage and provide essential nutrients.
Care
- Planting: Bare root raspberry canes are typically planted in the late winter or early spring before new growth emerges. Space plants 2-3 feet apart in rows 8-10 feet apart.
- Watering: Raspberries require consistent moisture, especially during fruit production. Water deeply at the base of the plant, allowing the soil to dry slightly between waterings.
- Pruning: Proper pruning is essential for maximizing yield and maintaining plant health. Prune primocanes in early summer to encourage branching and fruit production. After fruiting, remove floricanes that have borne fruit.
- Support: The tall canes of Caroline raspberry benefit from support, especially when laden with fruit. A trellis or stake system can help prevent the canes from bending or breaking.
The Caroline raspberry is a bush.

While it produces long canes that may seem vine-like, it doesn’t climb or sprawl like a true vine. It grows from a central crown at ground level, with multiple woody stems emerging from that crown. This characteristic growth pattern defines it as a bush.
